SASH-HOLDER.

SPECIFICATION forming part of Letters Patent No. 331,660, dated Decemberl, 1885.

Serial No. 174,739. (No model.)

To @ZZ whom, it may concern:

Beit known that I, CHAnLEs A. Seasons, a citizen of the United States,residing at Minneapolis, in the county of Hennepin and State ofMinnesota, have invented a new and useful Improvement in Sash-Locks, ofwhich the following is a specification, reference being had to theaccompanying drawings.

My invention has relation to improvements in sash-locks; and the noveltyconsists of the peculiar construction, combination, arrangement, andadaptation ofthe various parts for service, substantially as hereinafterfully set forth, and particularly pointed out in the claims.

Among other things, my invention has for its object to provide asash-lock which shall be capable of application to either sash of theWindow, to hold the same at any desired ad- Weights; to hold the sashagainst up or down movement when so adjusted, and to provide means whichshall combine strength7 simplicity, and durability of construction withcheap ness of manufacture, and effective and certain in action.

I have shown an embodiment of my invention in the acompanying drawings,referring to whichv Figure 1 represents a perspective view of a portionof a Window-frame, showing the sash in dotted lines. Fig. 2 is a detailperspective vienr of the loclr detached from the windowframe. v Fig. 3is a rear elevation of the lock in position in the frame. Fig. 4 is avertical sectional view on the line as x of Fig. 3, and Figs. 5 and 6are detail views of parts of my invention detached from the lock.

Referring to the drawings, in which like letters of reference indicatecorresponding parts in all the figures, A designates a Window-frame ofordinary Well-known construction, and B the sash of the design atpresent in use, a portion only of said frame and sash being shownherein, inasmuch as the invention will be readily understood by thoseskilled in the art. At suitable points in the frame A are providedrecesses or cutaway portions O, opposite the upper and lower sashes, andin said recessed or cut-away portions I provide or locate one of myimproved locks, D, adapted to act on said sash in juxtaposition thereto,and adapted to hold the same against movement when the sash has beenadjusted vertically, or up or down. The locks D are each ofsubstantially the saine construction, and I will now proceed to describethe same more fully by letter in the drawings.

E designates the base or supporting plate, on which the several partsare arranged or connected, and which is located in the recessed portionsof the frame A, said plate having arms a a, provided with apertures oropenings a', through which are passed screws or bolts b, to secure theplate in position in recessed portions of said frame, as clearly shown.rlhe outer vertical face of the plate E is recessed or cut away, as atc, and in said recessed portion o is arranged a cam-plate, F, said platebeing pivoted on a pin or stud, d, to said plate E,and havingthreeoutwardly-projectingarms, F F2'F3, arranged at diderent angles toeach other, and cast or formed integral with said plate, as shown. Theplate Eis provided with a rearwardlyextendiug solid portion, e, which isarranged at middle of the rear surface thereof, a short distance fromthe ends, to leave the projecting arms a a, and on the rear surface ofsaid solid portion e, at each side of the plate E, are providedrearwardly-projecting lugs or angesff, one arranged to project at cachend of said plate, and in a direction opposite to each other, the rearends of said lugs meeting on lines drawn beyond the middle of the plateE.

G Gr designate dogs or catches arranged on opposite sides of the plateE, and at opposite ends thereof, said dogs lying parallel with thevertical outer faces of the lugs f and outer edges of the plate E, andpivoted eccentrically to said lugs at their inner reduced or con tractedends, on a common pin or shaft, y, bearing in said lugs and passingthrough perforations in said dogs, which are loosely mounted thereon andare adapted to freely move or osoillate when acted upon by the camarrnsof the plate F, as will be presently fully described. The outer faces ofsaid dogs G G are broadened or made Wide,and corrugated, roughened, orserrated, as at g', thus enabling them lto take arm and secure bearingor hold in the sash B. The arm F of the plate F bears against the dog Gat the rear end of thei broadened bearing-surface thereof, which at thispoint is made plain or smooth; and the arm F2 of said plate, which ismade somewhat longer than the arm F', bears against the dog G in asimilar manner. When the cam'plate F is turned or oscillated by meanswhich I will presently describe, the arms F F2 are turned simultaneouslywith the plate and in opposite directions, thus forcing the dogs G Gdownwardly out of contact with the sash, and simultaneously.

The dogs G G are kept normally pressed outward, and in contact with thearms' of the plate and sash, by means of a spring, H,which is coiled orwound uponvthe common pivotshaft of the eccentric dogs g, as at h, andis provided with arms h, which extend in opposite directions on oppositesides of the plate, and having a hook, h2, bent or formed on the outerends of said arms and engaging one of the pivoted dogs G G.

I designates an operating-lever having a flange, t', cast therewith, anda pivot-lug, z, also cast therewith, through which lug i is passed a pinor stud to pivotally secure said lever in position upon asupporting-plate, I', secured by means of screws to the exterior face ofthe frame A, at some distance from the lock D, as clearly shown.

J designates a rod pivotally connected to an aperture in the tlange't'of said lever I, and at its opposite end to the arm F3 of the eccentricor cam-plate F. This connectingrod J passes through a slot or openingformed in the lower under surface of one of the strips or beads, J',which serves as a guide thereto.

In order to connect said rod to the lever, the outer end thereof is bentto form a lip, which is passed through the apertured flange of saidlever, and the inner end of said rod is bent, as atj, to bring the sameon a plane beneath the arm F3, to which it is pivotally connected, bymeans of an upt-urned end thereof, to provide a lip or stud, the plate Ebeing provided with a recessed portion, K, in which the end of the linkmoves, as is obvious.

It will be observed that the spring H keeps the dogs normally pressedoutward in contact with the faces of the sash, thus causing theoperating -lever I to assume a substantially vertical position, but whenpressure is applied to the outer end of said lever it is forced into ahorizontal position, which movement draws upon the connectingrod and theplate F, said plate being oscillated or turned so as to cause its armsto prese the dogs simultaneously away from engagement with the sash andagainst the action of the spring I-I, when the sash can be adjustedtoany desired position.

When the lever is in a substantially horizontal position, the rod Jimpinges against the lower end thereof, thus preventing the lever fromfurther movement and locking the same in position.

The operation will be readily understood from the foregoing description,taken in connection with the drawings.

By arranging the pivoted dogs or cams at of parts and details ofconstruction'may be made without departing from the principle orsacrificing the advantages of myinvention, the essential features ofwhich will be readily understood from the foregoing description, takenin connection with the drawings.

My improved sash -lock is very simple, strong, and durable in itsconstruction, thoroughly effective and automatic in operation, can bequickly and readily applied to window frames as ordinarily constructed,and cheap and easy of manufacture.

The link for connecting the canrplate and the operating-lever in thelock for the upper sash is made longer, and in the form shown in Fig. 6of the drawings, than the llink for the lower sash-lock, owing to thedistance from said upper sash to the point where it is nec- ICO essaryto locate the operating-lever on the window-frame.

Having thus fully described my invention, i

what I claim as new, and desire to secure by Letters Patent, is-

l. In a sashlock, the combination, with a window-frame, of asupporting-plate mounted in said frame, holding-dogs pivoted to saidplate, springs secured to the plate for actuating said dogs, a cam-platepivoted to the supporting-plate and having arms arranged to bear on theAdogs, a lever pivoted to the window-frame, and a link connecting saidlever and the cam-plate, as set forth.

2. The combination, with a recessed supporting-plate having rearwardlyextending arms, of dogs G, pivoted on acommon pin or shaft mounted insaid arms, a coiled spring arranged on said shaft and having bent armsadapted to bear onjthe pivoted dogs, a camplate pivoted to thesupporting-plate, and a lever pivoted to the window-frame and connectedto the cam-plate, substantially as described.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in presence of two witnesses.
